AbstractA method is presented for measuring C13/C12 isotope ratio of organic compounds by burning the material in a stream of normal CO2, separating the combustion products by gas chromatography and sequentially measuring the density of the enriched CO2 peak with a gas density meter. Data are presented for the analysis of enriched ethyl acetate from 15 to 1 percent enrichment. The method is applicable for other stable isotope analysis.
